We've all seen driers rated for small systems be installed on large systems. I recently did a job but questioned the drier size. 28 ton circuit with a c-305-s drier. Liquid line is 5/8. I was told to put it in and now have a 20-25lb psi drop between the discharge service valve and the liquid line valve after the drier. The system is a Trane RTU which had no factory drier. What do you think?
